Advanced Root Repair Material
india
1gr /3ml
Product Description : MTA is a powder &gel system consisting of an extremely fine, inorganic powder of Tricalcium and Di calcium Silicate, which sets with water or gel. The powder is
supplied in aprotective desiccant–lined container for freshness.
Composition : Powder consists of mixture of Calcium Oxide, Silicon Oxide, Bismuth Oxide and Gel is hydrated
polymer gel.
Indications : Dental procedures that contact vital pulp tissue such as : • Pulp capping, • Cavity lining, or •
Pulpotomies. Dental procedures that contact the periradicular tissues such as : • Root-end filling, •
Apexification, • Perforation repair, • Root resorption, • Sealing, or • Obturation (pulpectomy).
Contraindications :Hypersensitivity against caustic (high pH) solutions.
Warning : MTA powder is caustic, as are all calcium silicates.
Precaution : AVOID contact of unset mixed paste with skin or oral mucosa. After incidental contact, wash
and rinse with water. Wear suitable gloves and protective glasses during use. MTA powder and gel must be
kept well sealed. Protect the powder from humidity. Close the container. Do not contaminate the powder
with an unclean or moist Instrument. Do not overfill the root canals when obturating or sealing.
ADVERSE REACTIONS :Reversible acute inflammation of the oral mucosa if contacted with the unset paste.
INTERACTIONS WITH OTHER DENTAL MATERIALS :Unknown
STEP-BY-STEP INSTRUCTIONS :Dosage and Mixing : a) Dispense 1 scoop of powder on a
glass slab or a nonabsorbent pad. b) Dispense one small drop of gel, OR some of the MTA Liquid from 1
ampoule next to the powder. NOTE : The gelimparts washout resistance (for easier rinsing) and faster setting,
which the water does not. NOTE : MTA Liquid ampoules are larger than unit-dose size. c) Gradually mix the
liquid or gel into the powder until the desired putty like consistency is obtained. For some procedures, a
thinner syrupy, stringy consistency may be desired. Thoroughly mix to hydrate the powder. d) If the material is
not to be used immediately, cover the mixed material with a moist gauze sponge (use sterile water), or a clean
cover to prevent evaporation. Extra gel or MTA liquid may be used to rewet the powder before it sets.
Setting Time at 37°C : < 1 hr. when thickly mixed with gel. Film thickness :<50 μm when mixed

Application should be carried out strictly according to the directions for use. Liability cannot be accepted for
damages resulting from failure to observe the instructions of the stipulated area of application. The user is
responsible for testing the material for its suitability and use for any purpose not explicitly stated in this
instruction sheet. Descriptions and data constitute no warranty of attributes and are not binding.
DETAILED PROCEDURAL DIRECTIONS FOR USE :1. PULP CAPPING, PULPOTOMY or CAVITY LINER/BASE :
a. Complete a cavity preparation outline under rubber damisolation, using a high-speed bur and constant
water-cooling. b. Excavate all carious tooth structure using a round bur in a hand piece at low speed, or use
hand instruments. For a pulpotomy :Remove the roof of the pulp chamber and all remnants of coronal pulp
tissue to the level of the orifice of each root canal in multi-rooted teeth. In single-rooted teeth, remove the
pulp to the level of the cemento-enamel junction or slightly below this level. For a pulp exposure or
pulpotomy : Gently rinse the exposure with a saline solution. Control hemorrhage with pressure on the
exposure using a cotton pellet moistened with saline, a dilute solution of NaOCl (0.5 1.0%), or a mild
hemostatic agent. For a base/liner, pulp exposure or pulpotomy : Wipe the cavity preparation with a
chlorhexidine solution. Use a small applicator to apply mixed MTA material on the pulp exposure, or over the
floor of the cavity preparation. Remove excess material at the site with a dry cotton pellet. Rinse gently Place a
composite material or a glass ionomer restorative material over the MTA material. The glassionomershould
be an interim restoration prior to a placement of a final composite or other restorative material. Assess the
pulp vitality at three-month intervals or as needed and confirm with a radiograph.
2 . ROOT A PEXIFICATION or RESORPTION or PERFORATIONS : A. Debride, clean, and shape the root canal
system using intracanal instruments under rubber dam Isolation.b. Rinse the root canal with a NaOCl solution
(3.0 to 6.0%). For root apexification : Dry the canal system with paper points, being careful not to extend the
points beyond a wide-open apex. Gently compact MTA in the apical region, to create a 3 to 5 mm apical barrier.
Confirm placement with a radiograph. Rinse gently. Apply about 2 mm of a glass ionomer, acid etch, and place
composite. For resorption or perforations : Isolate the resorptive defect site or iatrogenic perforation.
Obturate the canal space apical to the defect. Dispense the MTA material into the defect site. Gently compact
the MTA material using a small amalgam plugger, cotton pellets or paper points. Confirm the placement with a
radiograph. Rinse gently. When the MTA material is firm (a few minutes), obturate the remaining canal space
and close the coronal access as you do normally.
3. ROOT-END FILLING : a. Surgically access the root-end and resect 2-4 mm of the root apex using a surgical
bur. b. Prepare a Class I root-end cavity preparation 3 to 5 mm deep with an ultrasonic tip. c. Isolate the area
and achieve hemostasis. Dry the area. d. Gently compress the MTA material into the root-end cavity using a
“plastic” instrument or other small carrier. e. Remove excess material and clean the root tip with a slightly
moist cotton pellet.f. Rinse gently. g. Confirm placement with a radiograph. h. Close the surgical site.
4. SEALING & OBTURATION OF ROOT CANALS : DO NOT overfill the root canals! When a large amount
ofmaterial is overfilled in the mandibular canal (inferior alveolar canal), immediate surgical removal of the
material should be considered, as with all root canal materials, according to stateof-the-art policy. a. Debride,
clean and shape the root canal system using intracanal instruments under rubber dam solation. b. Rinse the
root canal with a NaOCl solution (3.0 to 6.0%). c. Dry the canal system with paper points. d. For complete
obturation, gently compact the MTA material into the canals and ensure placement with a radiograph. e. For
filling techniques where most of the canal is obturated by endodontic point material, and apply a light coating
of MTA material (mixed with the gel to a syrupy, stringy consistency) to the canal walls. AVOID the formation of
air bubbles in the material. DO NOT use a pumping action. AVOID overfilling of the canal. MINIMIZE over
extension of the material beyond the apex. f. Coat the disinfect
ed and dried obturation points with the MTA
material and insert them in the Canal. g. Confirm placement of the material in the complete root canal system
with a radiograph.
Storage Conditions : Store at temperature between 10°C to 24°C. Close the cap carefully after use.
Keep away from moisture. Shelf life not affected after opening if stored in a cool dry place.
Warning: Avoid prolonged or repeated contact with skin (allergic contact dermatitis), and eyes.
Avoid prolonged inhalation. Do not take it internally. Contact with the skin may cause irritation,
burns of hypersensitivity. If contact with skin occurs immediately wipe off thoroughly with
